The present invention relates to a harvesting device suitable for laying and harvesting insect eggs for the subsequent growth of larvae. According to a second aspect, the invention provides a method for treating insect eggs using the aforementioned harvesting device.

To date, the nesting boxes are installed in aviaries and make it possible to collect the eggs of adult insects. However, the manual harvesting of eggs, their preparation, dosage and packaging for their handling and transport are time-consuming and laborious tasks. However, the insect larvae that come from these eggs are increasingly used as an ingredient in animal and human food, so there is an increasing need for large-scale egg collection. requires the installation of an automated system to meet demand.

One of the aims of the present invention is to propose at least one solution allowing large-scale collection under optimized conditions. To this end, the present invention provides a harvesting device suitable for laying and harvesting insect eggs, the harvesting device comprising:

supports, superimposed on each other, spacers, each of the spacers being interposed between two adjacent supports, among the superimposed supports, a spacer movable between a retracted position in which the supports are in the laying position, and a interaction position in which the supports are in the harvesting position, the movement of the spacer from the retracted position to the interaction position causing the supports to move from the laying position to the harvesting position, in the laying position, the spacers are in contact with the two respective adjacent supports, and define a laying space between the two adjacent supports, suitable for receiving the laying of insects, and in the harvesting position, each support is spaced an adjacent support with a distance D greater than the height of the spacer.

Thus, this harvesting device encourages insects to lay in selected locations, between two adjacent supports which are then mechanically separated to allow the harvesting of eggs. The collection yield is thus optimized.

Advantageously, the harvesting device comprises at least one guide element on which the supports are movably mounted, which facilitates the movement of the supports.

According to another arrangement, the harvesting device comprises at least two parallel guide elements, and the spacers and the supports comprise sliding means configured for sliding on the at least two guide elements. This configuration stabilizes the movement of movement of the supports, compared to the configuration comprising only one guide element.

Preferably, the supports have a mean plane and the guide elements extend in a direction substantially perpendicular to the plane of the supports, the at least two guide elements having a height configured to guide the sliding of all the supports between the position of laying and harvest position. In other words, the height of the two guide elements is sufficient to allow the arrangement in the harvest position of all the supports, which requires more space than in the rest position.

According to one possibility, each of the supports comprises a first end region and a second end region, opposite the first end region, the first end region and the second end region being slidably mounted on a first guide element and on a second guide element, and each spacer, interposed between two adjacent supports, being slidably mounted on the first guide element or on the second guide element.

According to one arrangement, the supports generally have the shape of a rectangle plate having a length of several tens of centimeters and a thickness of less than 2 cm.

According to a variant, each of the supports preferably has an elongated shape and extends in a general direction of extension, between the first end region and the second end region.

The length of each of the supports is between 10 cm and 2 m, preferably between 20 cm and 1 m, and more preferably between 40 and 60 cm. These dimensions make it possible to limit the weight and the size of the supports for greater ease of handling.

According to one arrangement, the width of each of the supports is between 2 and 4 cm. The height of each of the supports is between 1 and 2 cm. These proportions allow optimum efficiency to be achieved while retaining a weight compatible with automated use of the harvesting device.

Advantageously, the height of each of the spacers is between 0.15 and 10 mm and preferably between 2 mm and 5 mm so as to encourage the insects to deposit their eggs between two adjacent supports. The space between two superimposed supports is determined by the nesting habits of insects. The inventors have in fact observed that if the space is too large, the insects do not lay eggs, if it is too narrow, the insects cannot introduce their ovipositor so that few eggs are harvested.

According to one possibility, the harvesting device comprises between 2 and 40 superimposed supports.

Advantageously, the spacing member comprises at least two side walls extending opposite in a vertical direction, a bottom wall intended to receive the superimposed supports, a plurality of insertion parts mounted movably on each of the two side walls. to be separated from each other when the spacer is in the interaction position, each of the insertion parts being configured to be inserted between two adjacent supports, and and the displacement of the spacer from its retracted position to its interaction position generates an insertion of each of the insertion parts between two adjacent supports concomitantly with the spacing of each of the insertion parts between them, causing the supports to move from the laying position to the position harvesting by moving one of the two adjacent supports away from the other, in a direction substantially perpendicular to the directi one of inserting each of insert part.

Thus, when the spacer comprises as many insertion parts as there are pairs consisting of two adjacent supports, all the supports are moved from their laying position to their harvesting position in a simple manner and in one single step.

According to one arrangement, the displacement of the spacing member is carried out in the same direction as that of the insertion of each of the insertion parts between two adjacent supports.

Advantageously, the two adjacent supports each comprise a face delimiting at least in part the egg-laying space between the two adjacent supports and each insertion part comprises a tip-shaped end portion configured to exert pressure on a face of one of the two adjacent supports, so that the insertion of the insertion parts between the two adjacent supports and the spacing of the insertion parts between them causes the said face to move away from the other and the moving the supports from the laying position to the harvesting position.

As a variant, the tip-shaped end portion is configured to exert pressure on the two faces delimiting at least partially the laying space between the two adjacent supports, so that the insertion of the at least one insertion part between the two adjacent supports causes the two adjacent supports to move apart by the simultaneous separation of the two faces from one another.

Preferably, the insertion parts are regularly spaced along the side walls and the interval between two adjacent insertion parts in the retracted position of the spacer corresponds to the height of a spacer cumulated to the height of a support, so as to allow the arrangement of each of the end portions of the insertion parts opposite each of the spacers. It is thus possible to separate each of the pairs consisting of two adjacent supports from the harvesting device with the same amplitude.

The two side walls of the spacing member each preferably include a number of insertion parts identical to the number of spacers.

Advantageously, the harvesting device comprises a vibration member configured to apply vibrations to the supports when they are placed in the harvesting position, the vibrations being configured to cause the fall and recovery of the eggs coming from the laying of insects on the supports.

Preferably, the harvesting device further comprises a compressed air sweeping device configured to sweep compressed air laterally to the supports so as to participate in the detachment of the eggs. This scanning is advantageously associated with the application of the vibrations which it completes.

Advantageously, the air sweeping device is integrated into the spacer. A compressed air spray nozzle is disposed in each of the end portions of the insertion portions.

According to one possibility, the harvesting device comprises a container arranged under the superimposed supports so as to collect the eggs of insects.

Preferably, the container is disposed on the bottom wall of the spacer, the bottom wall itself being disposed on the vibrating member. Harvesting of eggs in the container is done during the application of vibrations. Advantageously, the container comprises a pivoting side wall configured to drop the harvested eggs into a weighing member arranged below and comprising a determined quantity of brewing powder, the weighing member being configured to determine the quantity of eggs present in the mixture by weighing and the weighing member comprising a brewing member configured to brew the eggs with the brewing powder in order to obtain a homogeneous mixture.

Preferably, the harvesting device comprises a dosing member configured to prepare portions of a predetermined quantity of eggs, the portions being intended to be packaged in individual packages formed of edible material or of water-soluble material. These packages are typically prepared from unleavened bread or gelatin. They are for example in the form of capsules.

Advantageously, the supports are covered with a non-stick product, configured to limit the adhesion of the laying eggs to the supports and facilitate their harvesting. The laying eggs have on their surface a laying mucus which can adhere to the support. The non-stick product limits the sticky effect of mucus.

The non-stick product is in particular a product known under the name of "TEFLON" (registered trademark), in which case the supports are covered with a coating of "TEFLON" ®.

According to an alternative embodiment, the supports are regularly coated with a non-stick product, consisting of a powder, mineral or organic, having a particle size between 1 and 1000 micrometers.

According to a second aspect, the invention provides a method for treating insect eggs, the method comprising the steps of:

a) Supply of a harvesting device as previously described,

b) Arrangement of the spacer member in the retracted position,

c) Arrangement of the supports in the laying position, so as to receive the laying of insects, and

d) Displacement of the spacing member in the interaction position causing the supports to move from the laying position to the harvesting position.

Thus this process allows the automation of the treatment of the laying and the harvest for a treatment on a large scale.

According to one possibility, the treatment method comprises carrying out a step e), after step d), of applying vibrations to the supports, so as to collect eggs in a container of the harvesting device. Vibrations are indeed effective in separating eggs from supports and harvesting them without touching or damaging them.

In addition to step e), the supports are covered with a non-stick product so that the effect of vibrations is more effective.

According to yet another possibility, step e) is carried out concomitantly with the application of a sweep of compressed air, in a direction lateral to the supports, so as to complete the action of the vibrations for detaching the eggs.

According to another possibility, the treatment method comprises carrying out a step f), after step e), of adding a determined quantity of brewing powder to a weighing member and harvesting eggs from the container. for the determination of the quantity of laying eggs collected and then stirring of the eggs with the stirring powder by means of a stirring member, so as to obtain a homogeneous mixture. Stirring allows the agglomerates of laid eggs to be broken up to homogenize the mixture well. The brewing powder is a mineral or organic powder, having a particle size less than or equal to 1 mm. The weighing device is configured to determine the quantity of eggs by weighing the mixture and simply subtracting the weight of the total mixture minus the weight of the brewing powder added. Generally the proportions of the mixture vary between 1/1 and 10/1 by weight respectively of brewing powder and eggs.

According to another arrangement, the treatment method comprises carrying out a step g), after step f), of preparing portions of a predetermined quantity of eggs present in the mixture via an organ harvester metering device.

The treatment method according to the invention comprises carrying out a step h), after step g), of packaging portions in individual packages formed of edible material or of water-soluble material. This step advantageously makes it possible, according to the proportions of eggs identified in the mixture, to prepare packaged portions of a determined quantity of eggs, ready to use for shipment to the customer. Upon receipt, the client must just place the portion on the larval food and the development of the larvae begins without requiring other manipulations. The determined quantity of eggs in each portion can be defined in the production standards, or left to the customer's choice, on a case-by-case basis.

The figures do not necessarily respect the scale of all the elements represented so as to improve their readability. In the following description, for the sake of simplification, identical, similar or equivalent elements of the various embodiments bear the same reference numbers.

Figure 1 shows a front view of the harvesting device according to a first embodiment of the invention.

Fig 2 shows a partial front view of the harvesting device in the harvesting position according to the invention.

FIG. 3 represents a partial side view of the harvesting device illustrated in FIG. 2.

FIG. 4 represents an enlarged and partial view of the harvesting device in the harvesting position according to the invention.

FIG. 5 represents an enlarged and partial view of the harvesting device in the harvesting position according to a second embodiment of the invention.

FIG. 6 represents a schematic side view of the harvesting device according to an embodiment of the invention.

FIG. 1 represents a harvesting device 100 in the laying position, comprising a superposition of supports 1, a plurality of spacers 2 each separating two adjacent supports 1, the supports 1 and the spacers 2 being mounted so as to slide on two elements of guide 3 extending parallel to each other, in a direction perpendicular to the mean plane of the supports 1. In the laying position of the supports, the spacers 2 are in contact with the two adjacent supports 1 between which they are interposed. Thus, the height of the spacer 2 determines the height of the laying space configured for the laying of the eggs O of the insects. Referring to Figure 1, the spacer 2 has a height of about 3 mm. According to a variant embodiment not illustrated and according to the species of laying insects considered, the spacer 2 has a height of between 0.15 and 10 mm and preferably between 2 mm and 5 mm.

The supports 1 are made of a rigid material, such as metal, plastic or wood. The first end region 4 and the second end region 5, opposite the first end region 4, delimit the largest dimension of each of the supports 1. They each include a bore configured to receive the guide elements 3 and allow mounting of the free supports 1 in sliding. According to an arrangement not illustrated, the number of guide elements 3 varies from one to several guide elements 3, all received in bores distributed over the length of the supports 1 so as to preserve the sliding. With reference to FIG. 1, the supports 1 have a length of approximately 50 cm, a height of approximately 1.5 cm and a width of approximately 3 cm (FIG. 1 does not maintain the proportions between the different dimensions for more readability). These dimensions make it possible to obtain a nesting unit 6, comprising the supports 1, the spacers 2 and the guide elements 3, which has the proportions below adapted to the dimensions of the rest of the harvesting device: approximately 60 cm long, 3 cm wide and 30 cm high.

According to an alternative embodiment, and according to the species of laying insects considered, this nesting unit 6 comprises dimensions which can vary between 5 cm and 100 cm in length, 3 to 10 cm in width and 5 to 60 cm in height (not illustrated). FIG. 3 illustrates a side view of the nesting unit 6 on which the section of the supports 1 is visible.

Referring to Figure 1, the harvesting device 100 further comprises a spacer 7 illustrated in the retracted position comprising two side walls extending opposite one another in a vertical direction, a bottom wall 10 and a plurality of insertion parts 8, one end portion of which has the shape of a point. Each insertion part 8 is configured to be inserted between two respective adjacent supports 1. The spacer 7 is movable between its retracted position in which the harvesting device 100 is in the laying position and an interaction position, illustrated in FIG. 2, in which each of the insertion parts 8 are inserted between two respective adjacent supports 1, and spaced from each other, causing the supports 1 to move to the harvesting position. Typically, each of the insertion parts 8 move apart, moving vertically, towards the top of the harvesting device 100.

In the embodiment illustrated in FIGS. 2 and 4, the insertion of the insertion parts 8 brings about the mutual separation of the two adjacent supports 1, with respect to one another, in a direction substantially perpendicular to the direction inserting the insert parts 8. More precisely, and as illustrated in FIG. 4, the tip end portion exerts pressure on each of the faces 9 of the two adjacent supports 1. This pressure, communicated by the translational movement of the spacer 7 towards the supports 1, causes the two opposite faces 9 to move away from one another, relative to one another. The space between the two adjacent supports 1 is increased until reaching a distance D greater than the height of the spacer 2, facilitating the harvest.

According to a second embodiment illustrated in FIG. 5, the tip-shaped end portion is configured to exert pressure only on one of the two faces 9 of the two adjacent supports 1, so that the insertion of the 'at least one insertion part 8 between the two adjacent supports 1 causes the displacement of only one of the two supports 1 until reaching the distance D suitable for harvesting.

With reference to Figures 1 and 2, the height of the guide elements 3 is chosen so as to allow the spacing of all the supports 1 with respect to a respective adjacent support 1, until at least the distance is reached Of them. Two abutment members 11 are fixed on each end of each of the guide elements 3 so as to maintain the supports 1 and the spacers 2 on the guide elements 3 during their sliding, when the supports 1 move between the laying position and the harvest position.

As illustrated in FIG. 1, the harvesting device 100 further comprises a vibration member 12, on which the bottom wall 10 of the displacement member 7 rests, configured to apply vibrations to the supports 1 when they are placed in harvest position. The vibrations applied are for example of an amplitude between 1 to 30 mm and a frequency of 0.5 to 100 Hertz so as to allow the collection of the eggs O of laying in a container 13 placed on the bottom wall 10 of the spacer 7 and in which the supports 1 are arranged, the area of which is at least equal to that of the nesting unit 6.

According to an arrangement not illustrated in FIG. 1, the harvesting device 100 further comprises a compressed air sweeping device, configured to propel compressed air towards the eggs and participate in their detachment from the supports in association with the application of vibrations.

According to an arrangement not visible in the figures, all of the supports 1 are prepared so as to limit the adhesion of the mucus on the surface of the eggs O on the supports 1 and complete the action of the vibrating member. The preparation is carried out by applying a non-stick product to the surface, such as coating a product known under the name of "TEFLON" (registered trademark) or by coating regularly repeated with a dedicated powder.

As illustrated in FIG. 6, the harvesting device 100 comprises a weighing member 14 into which the eggs initially collected in the container 13 are poured by pivoting a side wall of the container 13 associated with vibrations generated by the picking member. vibration 12. This weighing member 14 contains a brewing powder, mineral or organic, having a particle size between 1 and 1000 micrometers so as to undo the egg agglomerates bonded together. This weighing member 14 determines the quantity of eggs harvested by subtracting the full weight minus the weight of the brewing powder added. The weighing member 14 further comprises a stirring member 15 making it possible to stir the eggs O in the presence of the stirring powder so as to obtain a homogeneous mixture. The harvesting device also comprises a dosing member 16 configured to prepare portions 17 of a predetermined quantity of eggs, the portions 17 being intended to be packaged in individual packages formed of edible material or of water-soluble material.

A method of treating insect eggs O according to a second aspect of the invention and using the harvesting device 100 is now described in relation to FIGS. 1, 2 and 6. This method comprises successively carrying out the following steps, comprising a step a) of supplying a harvesting device 100 as illustrated in FIG. 1, a step b) of arranging the spacing member 7 in the retracted position, as illustrated in FIG. 1, a step c) of arrangement of the supports 1 in the laying position, so as to receive the laying of insects, then after a day, or once the laying nest 6 is full, a step d) of displacement of the organ of spacing 7 in the interaction position is made, so as to cause the displacement of the insertion parts 8 towards the two respective adjacent supports 1, generating their spacing, until reaching a distance D, by sliding the supports 1 and the spacers 2 on é guide elements 3.

Once the supports 1 in the harvesting position, a step e) is carried out by applying vibrations to the supports 1, by means of the vibration member 12, so as to collect eggs O in an underlying container 13 . This harvesting step is followed by a step f), consisting in adding a determined quantity of brewing powder into a weighing member 14 and in brewing the eggs O poured from the container 13 with the brewing powder until a homogeneous mixture, with a brewing member 15. The quantity of eggs O present in the mixture is determined with the weighing member 14 by simple subtraction of the weight of the total mixture minus the weight of the brewing powder added.

Then a step g) of preparing the portions 17 of mixture of a predetermined quantity of eggs, corresponding for example to the customer's wish, is carried out via the dosing member 16. Each portion is then packaged in a package individual in step h). The packaging consists of edible material or water-soluble material.

The determined quantities of eggs in portions 17 can be chosen by default, or according to the customer's choice, on a case-by-case basis.

Thanks to these individual packages, the eggs are protected, they can be handled easily, for example in a subsequent breeding of insect larvae. The eggs are then placed in breeding tanks, for example on a moist food, which allows the partial dissolution of the water-soluble packaging making it more easily passable by the mini-larvae which appear when the eggs hatch.

Once the eggs O are harvested from the supports 1 according to steps a) to e) of the process, insects are invited to lay again while the eggs O previously harvested are stirred, dosed and packaged according to steps f) to h) of the process.
